Make explicit statement that C++ compiled "to native machine code" (#521)

* Make explicit statement that C++ compiled "to native machine code"

All main implementation of the languages in the example (Java, C# and Python) are actually compiled to bytecode. IMHO it's better to clearly add explicit statement that C++ is compiled "to native machine code" unlike this languages to avoid ambiguity.

* Update talk/introduction/goals.tex
